Do I need a permit for addition or structural alteration in Irving?
Yes. In Texas, addition or structural alteration generally requires a permit, and Irving is no exception.
Additions to a Texas home almost always require a building permit plus separate trade permits, and enclosed additions trigger full residential plan review. Outside city limits, county authority over residential building is limited, so confirm which office has jurisdiction over your property before starting. A permit is required to erect, enlarge, alter, or move a structure in Irving, so an addition that adds floor area or changes structural elements needs a permit under the adopted 2021 International Residential Code. If the homeowner plans to do the work themselves, Irving requires a homestead exemption to be on file with the Dallas Central Appraisal District before a residential permit is issued (roof permits are an exception). The addition must satisfy the setback, height, and lot-coverage standards of the Irving Unified Development Code, and a floodplain development permit may also be needed near the Elm Fork of the Trinity River or other creek corridors.
